Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic Asian beetle accidentally introduced into North America before 2002. Its larvae feed on and kill ash trees, creating regulatory headaches and costing millions in control measures. In July 2008, a small EAB infestation was discovered at a Wappapello Lake campground. Since then, the beetle has been detected in several other areas in the state.
You can help slow the spread of the emerald ash borer by detecting it early in your area. Use the Emerald Ash Borer brochure below, and report signs of EAB to forest.health@mdc.mo.gov.
